1. Preface

 

Congratulations on purchasing a Robocrop precision guided implement. 

Robocrop precision guided implements are guided by a computer controlled steering system. 

There are 3 main components to the system. 

1.  A  digital  camera or  cameras  mounted  on  the  implement  looking  ahead  at  a  wide area of 

crop normally taking in several rows.  

2.  A cab mounted console  containing a computer  to  analyses camera images and find exact 

row centres.  

3.  A  hydraulic  side  shift  (or  steered  discs)  controlled  by  the  computer  to  keep  the  camera 

centrally over crop rows and the implement precisely on track.

Robocrop uses a colour camera to pick out green crop and weed from backgrounds containing 
soil, stones and trash.  (Consult your Garford dealer for systems to work in red crops.)   Robocrop 
locates crop rows within a scene by matching a template corresponding to the known planting 
pattern with crop rows as they appear in the camera image.  That image is displayed live on the 
console with the template overlaid as green lines. 

Matching a template to a broad area of crop rather than locating individual rows improves reliability 
especially when parts of those rows are not present or obscured by weeds.  Template shape is 
determined by a configuration file pre-programmed to suit a particular crop planting geometry and 
implement configuration.  Different configuration files can be created for different crops and 
implements. 

A good match between the template and crop rows is very important for accurate row following.
